// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details

//require告知Sprockets要加载的文件
//require_tree告知sprockets递归引入文件夹下的js文件，文件夹的路径必须相对于清单文件，也就是当前文件
/*３．可以使用require_directory指令加载指定文件夹中的全部js文件，不过不会递归就是了。
*　４．require_tree 指令加载的文件是无序的，如果加载的文件有先后依赖关系的话应在之前用require指令显示加载进来。
